PETER HENRY HOLTZ, OF DETROIT, MICHIGAN.

GARBURETER.

Application filed August 29, 1917.

To all Iwhom it may concern Be it known that I, PETER HENRY Hol/rz, a citizen of the United States, and a resident of Detroit, in thc county of Wayne and State of Michigan, have invented a new and Improved Carbureter, of which the following is a full, clear, and exact description.

The object of the invention is to provide a carburetor suitable for the Carburation of air7 and it is characterized by means for imparting a rotary movement to the fue! and the air to better carburet the air.

To obtain the above result I provide u carburetor `with a plurality of revoluhle disks between which the fuel is admitted, and also air to be carbureted. The air helps to break up and to thin the oil between the disks. i

Other characteristics of the invention will appear as the description proceeds.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in -all the views.

Figure 1 is an axial section through a carbureter embodying my invention;

Fig. 2 is a plan view of the cup into which the liquid hydrocarbon is fed;

Fig. 3 is a plan view of the surface of the disk facing the bottom of the cup;

Fig. 4 is a plan view of the upper surae of the disks between which the air is Fig. 5 is a plan view of the fanlike mixer disposed above the main air inlet of the carbureter; and

Fig. G is a top plan view of the cone disk located above the mixer.

Referring to the drawings, `7 is the lower section of the carbureter housing and 8 is the upper section which forms the dome. The; two sections are connected to each other by a spacing ring 9 which has arms 9 extending to engage the dome and which provides an annular ap 10 between the two sections to form te main air inlet to the carbureter. The height of the gap may be varied by a ring 11 threaded on to the dome 8. The ring 11 has a curved apron 12 which cooperates with the inwardly-directed curvature of the ring 9 so as to cause the air to flow toward the axial part of the dome.

The lower arof section 7 of the housing accommo ates the mechanism for va- Specication of Letters Patent.

porizing the liquid hydrocarbons, and it comprises a series of superimposed disks of which 13 is in the shape of a shallow cup having a tubular stem 14 rcvolubly mounted in the bottom of section 7 to be coaxial with the housing. The projecting end of the tubular stem li is surrounded by a fuelsupply chamber 15 to which liquid fue] is supplied through a conduit 16. Dmcrtures- 17 are provided within the stom 14 which bring the same into comuiuniration with the chamber 15. Preferably the bottom of the cup tapers or slopes` inwardly and it is provided with spiral grooves 18 which facilitate the movement of the fuel outwardly.

Positioned within the cup is a disk 19 the lower surface. of which has also spiral grooves 18. In addition it is perforated to allow the oil to travel t0 the upper surface of the disk. The disk 19 has a tubular stem 20 coaxial with the stem 14. The annular space formed by thc stems 14 and QQserves as a conduit for the fuel to thecup. The annular space closed at `the lower end of the stem 14 by a member 21 carried by said stem and which serves as a bearing for the lower endl of the stem 20. The stems 14 and 20 are each provided with a gear 22 and 23 respectively which are in mesh with gears 24 and 25 driven from independent shafts so to revolve in opposite directions, the gears and shafts being indicated in dotted lines.

The cup 13 with the stem is displaceable along the axis by a spring 26 so that the clearance between the c up 13 and the disk 19 will vary with the speed of rotation and, therefore, the feed of fuel between the two adjusted. It is evident that the higher the centrifugal force the less will be the clearance between the cup and disk and, therefore, the more rapid will be the breaking up of the fuel passing therebetween.

To increase the disintegration of the liquid hydrocarbons I provide an additional pair of superimposing disks 27 each provided with perforations therethrough and annular grooves 28 on the upper face there of. The two disks have coaxial tubular stems the annular space 30 between which serves as an air conduit to the space between said disks 27. The two stems at the lower end thereof are provided with gears 31 each in mesh with a corresponding gear 32, the two gears 32 revolving in opposite directions whereby the two disks 27 are revolnble oppositely. The air enterin the passage 3() is driven outwardly by ao centrifugal force and comes in contact with the hydrocarbon passing thereto through the perforations in the lower disk 27 and helps to break up this hydrocarbon and7 in conse quence, facilitates the evaporation of same. The frictional resistance of the disk surfaces also aids the evaporation of the liquid hydrocarbon.

The vapor 2T and near t Jassing through the upper disk 1e margin of same is detiected by the ring 9 toward the central part of the dome, and as it passes to the dome it entrains the atmospheric air through the gap 10` The vapor and air are entrained by a fanlike mixer 83 which is in the shape of a shallow inverted cone the tubular stem of which projects through the tubular stem 2.) of the upper disk 27 whereat a gear 34 is provided which meshes with a gear 35 Yfor revolving said mixer in a direction opposite` tothe upper disk 27. The mixer, in addition to mixing the air with the vapor forces the mixture through a perforated shallow conical cup 36, the inner surface of which cup has annular grooves 37 and spiral slots 3S. This cup has also a tubular stem passing through the stem of the mixer and provided at the lower end with a gear 39 which is in mesh with a gear 40 to be revolved in a di rection opposite to the mixer. A similar cup 41 is provided Within the cup I-Sl. lt has :i stem 42 passing through the tubular stem of the cup 36. A gear 43 is secured to the lower end of the stem 42 and it meshes with a gear 44 whereby it is revolved in a direction opposite to the cup 36.

T he dome 8 has a partition 45 which enters the cup 41 so as to present a suh` stantially uniform clearance therebetween. Spring-held valves 46 are provided in the partition to open into the chamber 47 which is formed by the partition and the top ot the. dome. The outlet from the chamber is controlled by a bntterfiy valve 48 of the rustomary construction.

The, ressure generated by the mixer 2&3 not ony drives the mixture through the, cups 36 and 41 but also through the valves 46 into the chamber, from where it is taken by the engine suction.

The invention is not confined to the particular details of construction shown and described as exemplifying the same but is capable of embodiment in various forms which,wi1l readily suggest themselves to one skilled in the art provided the modifications fall within the scope of the claims.
